Sun in OIII and Ca-K

In the late afternoon I took some pictures of the Sun with Sunspots AR2859 and AR2860.

Setting : Nikon D7500 and TAL200K with Solarfilm ND3.8 and ND3.8 with OIII filter and ND3.8 with Ca-K filter

Green Flash

I was looking at my pictures taken taken during my vacation at the Belgian Coast @De Panne. On July 18th I was able to take a picture of Green Flash - see my blog  but  also on July 17th. When looking at the details of the those pictures I saw aswell a Green Flash. This time the flash was observed a little above the horizon. The Green Flash on July 18th was a little higher above the horizon. 

To conclude: I was able to photograph twice a Green Flash during my holliday. Really Cool!

Editing Sun H-Alpha

I reworked my picture of the Sun which I made yesterday - see this link
The bright and enormous prominence has now more contrast. 

Sun in H-Alpha

This afternoon I observed the Sun in H-alpha using my SolarMax III d70/400 f/5.3 DS BF15. The spotless sundisk showed a couple of big filaments and one huge prominence. 

The picture was taken with Nikon D7500, ISO400 and 1/320s. Editing using CS4.

NOSS Double in Milky Way

Only one bright perseid meteor and a couple of faint ones during an hour observation from UT20h15-21h30 on August 13th. As the sky was very clear I decided to take some pictures of the milky way using my wide field lens 10-24mm. It's clear that the sky is overloaded with satellites and satellite debris as all of my pictures have at least one satellite trace. The picture shows a double trace of the Naval Ocean Surveillance System. This "NOSS Double" is formed by NOSS 3-7(A) and NOSS 3-7(R).
